Openair-Plasma: A Versatile and Reliable Solution for the Electronics Industry


By the Staff of Plasmatreat


be aware that this umbrella term covers two different processes. Vacuum plasma treatment and atmospheric-pressure plasma treatment are both based on the same technology, but the areas of application are quite different. Most electronics manufactur-


T


ers associate the term plasma with the use of vacuum plasma, which is very much embedded in front-end and back-end applica- tions in the electronics industry. The process of atmospheric-pres- sure plasma, also known as Openair-Plasma®, has been used for more than 20 years in a wide variety of applications. Openair- Plasma has significant advan- tages due to its selectivity, inline capability and the resulting speed of surface treatment. Even small and medium-sized electronic


reating surfaces with plasma is a stan- dard process in today’s electronics industry, but potential users might not

plasma pretreatment for the electronics This technology removes release agents


and additives from surfaces. The process is based on specific jets that produce a safe, zero voltage plasma and thus do not affect components and lay- outs. Besides ultra-fine cleaning, plasma activation of the surface can follow, which improves the later adhesion of materials, such as paints, for example. The PlasmaPlus® activation

industry are obvious: the Openair-Plasma generated in a special plasma jet can be applied with accuracy and selectivity to a wide variety of components and geometries.


process can apply a functional nanocoating to the surface. The use of Openair-Plasma thus is particularly well suited for appli- cations in component manufactur- ing in which special surface prop- erties are crucial for further pro- cessing, for example in printed circuit board production, confor- mal coating or in display and com- ponent manufacturing. Openair-Plasma treatment is a cost-efficient and production-safe


process that is used in a variety of applica- tions within electronics manufacturing. Plasma treatment gives manufacturers sig- nificant advantages over their competitors. Continued on next page
